Title: Method for solving optimization problem by means of genetic algorithm
Inventor: UEKI KOICHIRO
IPC: G06F15/18
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To fast and surely solve an optimization problem by coding newly a common part included in a set of solutions whose evaluation value are approximate to each other and then performing the heuristic retrieval of solutions for every code. SOLUTION: A group of solutions are ranked according to their evaluation value which are decided by an evaluation function and the sets of solutions are successively composed in the order of adjacent ranks. Then the parts which cross each other are decided by a monotonous increment function having the saturation characteristic and according to the ranks of sets of solutions. A common part of the solutions included in the same set is newly coded after the two parts crossed each other, and the heuristic retrieval of solutions are performed for every code in regard to the coded part. Then the coded part is decoded, and the heuristic retrieval is performed again in a range where a single code is composed also for the coded part. This processing is repeated to optimize a solution.

Title: Flow controller for power steering
Inventor: KUGIMIYA FUSAYOSHI
IPC: B62D5/06
Filed: 1982-06-18
Abstract: PURPOSE:To improve the flow control accuracy by reducing the flow in the high speed region of pump irrespective of load variation of power steering thereby directly applying the dynamic pressure of pump port onto the spool for controlling the bypass flow. CONSTITUTION:Upon increase of feeding amount of a pump port 2, to increase the differential pressure to be produced by a through-hole 20 above predetermined level, a spool 7 will retreat against a spring 10 to open a bypath port 4. A portion of the operational oil in the pump port 2 is bypassed to the reservoir side to maintain the pressure across the through-hole 20 constant thus to maintain the flow to the feed port 3 constant even if the rotation of pump has varied. The piston body 8 is positioned through ballancing of the dynamic pressure from the pump port 2, sum of the pressures in front and rear of a variable orifice 21 and the spring force 15 thus to maintain the opening of the variable orifice 21 constant irrespective of the load pressure and to prevent increase of flow.

Title: Crt display device
Inventor: SHIGA AKIRA
IPC: G09G1/16
Filed: 1988-04-27
Abstract: PURPOSE:To reduce partial CRT screen burning by providing a timing adjusting circuit which varies the line display timing of a display part and a flip-flop circuit which controls whether the circuit is effective or ineffective between a vertical synchronizing signal generating circuit and a CRT display part. CONSTITUTION:The vertical synchronizing signal generated by a vertical synchronizing signal generating circuit 9 is inputted to the timing adjusting circuit 12 to determine whether or not the timing of the vertical synchronizing signal is adjusted by a flip-flop circuit 11 whose output value is inverted every time the power source is turned. When the timing is adjusted by the flip-flop circuit 11, the timing adjusting circuit 12 shifts the vertical synchronizing signal to n/m [where (n) and (m) are integer and (n)<(m)] times a display character line, i.e., a demultiple of one line, so the display line of CRT display 3 is shifted every time the power source is turned on. Consequently, display information is fixed and the same display part is made to illuminate, thereby reducing the screen burning at the display position.

Abstract: PROBLEM TO BE SOLVED: To surely separate and align confectionery or the like by decompressing and sucking confectionery to be moved, and blowing out the pressurized gas from a sucking bill when it reaches a desired position, thereby forcedly separating the confectionery from the sucking bill. SOLUTION: Many small holes are bored in suction cup 6a (e.g. circular) of suction pipes 6 arranged side by side and fixed to the peripheral wall of one cylindrical drum 5, air is discharged as shown by arrows 28, 29 from a discharge port 13 to decompress the decompressing sections 30 of the cylindrical drum 5. While the inner end of the suction pipe 6 faces on the decompressing section 30 (decompressing chamber), sucking force is generated in the suction cup 6a. Then, the confectionery dough is sucked, and with the rotation of the cylindrical drum 5, the suction cup 6a to which the confectionery dough is sucked is also rotated in the same direction. When the inner end of the suction pipe 6 thus enters the pressurizing chamber 19, the pressurized air in the pressurizing chamber 19 flows in the direction of an arrow 32 to blow off the pressurized air from the suction pipe 6, so that the confectionery dough separates from the suction cup 6a and drops on a conveyer operated at a suitable speed to be sequentially aligned.

Title: Production of electronic circuit board
Inventor: KINOSHITA SHINGEN
IPC: H05K3/34
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To obtain a production system of electronic circuit board in which ordinary combination of a print mask and a squeegee can be employed in printing process by performing the printing process in advance of the part arranging process of each mounting technology. SOLUTION: When a board 1 is produced, a solder printing process is performed at first followed by a fixing agent coating process and a chip mounting process. More specifically, the solder printing process is performed before an electronic circuit part, e.g. an IC chip, is mounted and a protrusion is formed on the board 1 in each mounting process. When the solder printing process is performed in advance of each mounting process, a special print mask, e.g. an emboss mask, requiring a long term for production or a squeegee of low hardness is not required but ordinary print mask and squeegee can be employed. Consequently, production time of print mask is shortened and a sufficient quantity of cream solder can be printed on the board 1.
